Need a new one…….

……this historic artefact is at least 11 years old, possibly older……I don't use it much (the odd call when I'm out and about, an occasional text, I never get anywhere near my monthly contract allowance) but the battery is obviously on its last legs and it's refusing to 'connect' with my Ma's new panic alarm……definitely NOT looking forward to the renewal process…..suggestions for replacement models gratefully received…..pray for my soul…….
